Mission Statement

COSI Mission Statement

Through training, continuing education, and ongoing support, we equip individuals to leverage the capacity for human connection by applying the radical simplicity of the Circle of Security to learning while honoring people’s strengths and struggles to build trust and find coherence.


On Culture, Trauma, and Resilience

We recognize that how we see the world is shaped by both our experiences and our culture. We seek to honor what we call positive intentionality.

Equity, Connection and Belonging Statement

At Circle of Security International, connection, equity, inclusion, and racial justice are at the core of who we are.

Company History

Circle of Security began in 2008 in response to growing demand for training in the COS-Intensive intervention. As interest grew, so did the company.
